well its not bad strange just odd. when im going after i start her up. i let it run for like 20 seconds then go. as i come to a stop while it is cold i push in on clutch look at my rpms and they dig down to 100 sometimes 0 and it shakes for a min and bounces up to 1k and stays im wondering if one of my sensors went out or if i have a cloged line or something. any help will be appricated.

 

hey man sounds like to me you have a clogged line srry i cant help anymore then that never experienced it

 

i have a feeling its a vacuume line i need to check themout.

 

i'd check the maf, might need a cleaning, it also sounds a lot like an IACV to me from my experiences, check both, tell us what it is when you find it, i keep hearing about more and more of these symptoms. also make sure your idle air screw is adjusted properly. Is idle when its warm normal? if so, its not the Idle air screw...probably one of the others.

 

it could be the MAF. Is ur car turbo, cause if it is then when u let off coming to a stop sign it would bog cause it has a MAF sensor.

 

S13 KAs have a line going to the intake air box. Unplug it & see if that helps. Regardless, spray 1/2 can of F.I. carb cleaner in there.

were do you buy your gas? ive gotten crap tanks of gas from those mom and pop stations, and ive had the very same experiences your having. try and stick to shell, chevron and such.

 

typically with vacuum leaks, the idle goes low-even stalls sometimes. so it wouldn't cause the idle to raise to 1k rpms...check what i said in my first post then tell us if that helps at all.
